Summary
The Robokassa payment gateway for WooCommerce WordPress plugin before 1.9.0 does not verify the authenticity of incoming payment-notification requests before acting on the order named in them. An unauthenticated remote attacker can force any WooCommerce order into a failed state, and because order identifiers are sequential, every order in the shop can be removed from the fulfilment queue. The weakness is classified as CWE-862 (Missing Authorization). A public exploit is linked in the references.
